Mount & Blade:Warband (Imagine Total war series FPS style, with hundreds and maybe a thousand soldiers in the battlefield and you are right in the middle of it)
The Guild 2 (Medieval family dynasty sand box game. The initial release was buggy as hell but everything has be fixed. And you can have kids and career to be a criminal. Total time sink)

Nothing new for me imho... but some old stuff that people should really try out

Dreamcast: Test Drive Lemans (perfect blend of arcade/sim imho)
PS2: Front Mission 4 (sold like crap, but I really enjoyed it)
PC: Jagged Alliance 2 Gold (super old and still just as awesome as the day I played it)
Xbox1: The Red Star (awesome arcade game, it's on PS2 as well)

Stuff I like on current gen PS3/360 are the popular stuff, deadspace/halo/demon soul/etc.

Big in Japan and Asia, fairly low-key in North America. Orginally I thought it was due to the difficulty, but Demon/Dark Souls seems to have taken to these shores fine, and really Monster Hunter deserves whatever success it gets - one of THE best franchises Capcom has built or nurtured, imo.
